A seat unit for a passenger of an aircraft, the seat unit comprising:

• a seat with an adjustable position and a shell configured to isolate said seat from neighboring seat units, said seat including a sitting portion and a backrest movable on a base, said sitting portion and said backrest being actuated by a respective motor-driven mechanism, wherein the seat unit further comprises a means for detecting a presence of said passenger on the seat, said seat being configured to:
• adopt a takeoff/taxiing/landing position when a presence of the passenger is detected by said detection means, in which said sitting portion is positioned a predetermined distance from said shell and in which said backrest is reclined in the direction of said shell, and
• adopt a docking position when no presence of the passenger is detected by said detection means, in which said sitting portion is positioned at a distance less than the predetermined distance from said shell, and in which said backrest is substantially parallel to said shell, so as to widen a passage formed between said seat and a respective neighboring seat unit arranged in front of said seat, or a wall of the aircraft, when said unit is installed in an aircraft cabin of the aircraft.
